Likurg_2 [28]

Answer:

The adaptive immune response is divided into two branches. The first is immunity, in which antibodies are produced that bind to the foreign cell. In the second branch, immunity, recognizes foreign cell structures and can destroy or help activate infected cells, which can generate plasma cells that produce specific antibodies.

Explanation:

Specific antibodies are those proteins that mark certain pathogens, these are manufactured by cells of the immune lineage, and the acquired defense, that is, the one acquired by humans during their growth, is not born with these antibodies.

Specific antibodies are formed once a pathogen has been recognized, that is, in the second encounter between the pathogen and the organism, that is why we are talking about a first infection and a second infection.

These antibodies are recognized as those that are formed in some vaccines.
